I'm not sure about blocking only streaming, but transferring mpeg2 over
the tubes is going to be a time consuming process unless you have fiber at
both ends.
Have you considered having an isolated remote myth box and setup all of
your recordings with a userjob that starts nuvexport after each recording?
You could then transfer your (significantly smaller) recordings through
These episodes wouldn't be integrated with the rest of the recordings, but
you could watch them in mythvideo and set nuvexport to output the file
with the recording name, date and episode title.
